Question

The run indicator on the CPU is flashing. What's wrong?

Answer

The CPU has gone into update mode. This can be caused by an electrical spike to the incoming power or by the relay outputs, if powering an inductive load without using proper surge suppression.

To correct this problem, you will need update the firmware. You will need the Koyo Support Tool and DL105 Firmware file

If your issue was relay output related, please see AN-MISC-032 for correcting relay transient issue.
